When people are happy, they can spray some perfume to express their emotions, and the car will also use scents to express emotions. Different smells represent malfunctions in different parts of your car. Will your nose be repaired?
A moderncarIt consists of at least 7000 parts, these parts are metal, plastic, and rubber, each of which has a different flavor. Of course, most parts have a small smell under normal working conditions, but once a certain part of the parts is abnormally worn or consumed, it will give off some pungent smells, such as burnt smell, bad smell, and There is a plastic smell... Today we will teach you to use these smells to judge the breakdown of your car.
Odor type: strong burnt smell
Cause: the clutch disc is burned or the handbrake is not loosened
I smelled a special smell of burning non-metallic materials during driving, which is usually car-lovingclutchThe friction plate is burnt, too thin or overheated. This kind of smelt is usually mixed with burnt smell, because the material of the clutch plate is compounded by various materials such as rubber and asbestos.
If the clutch is used normally, and there is no obvious difficulty in gearing or starting difficulties, and the smell of getting off the car does not come from the front of the car, but the rear of the car, then we have to check the rearBraking SystemWhether there is overheating, some careless car owners still force the car to walk while pulling the handbrake, which will cause the rearBrake padsHugged, giving off a burnt smell.
Odor type: plastic odor in the cab
Cause: Overheating of wires or short circuit of electrical appliances
If it is the smell of plastic products coming from the car, it is mostly caused by the overheating of the electrical wiring.It should be noted that the outer sheath of the wire is generally thin, so even if the wire has overheated, the smell will not look likeClutch plateIt’s as big as it burns. However, the burning of wires is usually accompanied by local smoke or local heating. As long as you carefully check, you can definitely find the source and determine the fault location.
Once the wire is overheated, it is necessary to stop immediately to find out the reason. Don’t look at the smell of the wire burnt, but the danger index is very high. Under normal circumstances, there will be more cases of excessive wire temperature in spring and summer. If not, Discovered in time, it is easy to cause complete circuit damage, engine cylinder pull, and even spontaneous combustion of the entire vehicle.
Odor type: the smell of mixed combustion of engine oil and gasoline
Cause: The oil jumped into the cylinder chamber to participate in the combustion
This kind of smell is generally rare, but you will generally not make a mistake when you smell it.Because the ignition point of engine oil is different from that of gasoline, it is impossible for the engine oil to be completely compressed and burned in the cylinder. At this time, there will be a small amount of engine oil particles fromexhaust pipeExhaust, which is what we commonly call blue smoke.
First of all, blue smoke from gasoline-powered cars is definitely an abnormal phenomenon.Under normal circumstances, the oil should only be in the oil passage against the cylinder wall andpistonLubrication, but once the inner wall of the cylinder is severely worn or the piston is severely worn, the oil originally in the oil passage may enter the engine combustion chamber. In addition,ValveA heavily worn engine may also burn oil. In addition, the oil pipes of some vehicles are aging and leaking, and oil may drip onto the engine or exhaust pipe. At this time, the smell of oil may cause a fire.
